     Diatomite sefa rubatsiroine yakanaka microporous chimiro, adsorption performance uye anti-compression performance, iyo isingangogonese iyo yakasefa mvura kuti iwane iri nani yekuyerera mwero reshiyo, asi zvakare inosefa kunze kwakanaka kwakamiswa solids kuve nechokwadi kujeka.

     Diatomaceous pasindiyo dhipozitizvezvisaririra zvekare-sero rimwe diatom. Hunhu hwayo: huremu huremu, porous, simba rakakwirira, kupfeka kuramba, insulation, kupisa kupisa, adsorption uye kuzadza uye kumwe kuita kwakanakisa. Iine kugadzikana kwakanaka kwemakemikari. Iyo yakakosha maindasitiri zvinhu senge kupisa kupisa, kugaya, kusefa, adsorption, anti-coagulation, demoulding, kuzadza, mutakuri uye zvichingodaro. Inogona kushandiswa zvakanyanya mumaindasitiri akadai sesimbi, indasitiri yemakemikari, simba remagetsi, kurima, fetiraiza, zvekuvaka uye zvigadzirwa zvekudzivirira. Inogona zvakare kushandiswa seindasitiri inoshanda mafirita epurasitiki, rabha, ceramics, uye kugadzira mapepa.

Diatomite sefa yekubatsira kupatsanura Diatomite mafirita aids akakamurwa kuita zvigadzirwa zvakaomeswa, calcined zvigadzirwa uye flux calcined zvigadzirwa zvinoenderana neakasiyana maitiro ekugadzira.

①Chigadzirwa chakaoma Iyo yakacheneswa, yakafanoomeswa uye yakapwanyika yakaoma silica ivhu mbishi inoomeswa patembiricha ye600-800 ° C, yobva yapwanywa. Ichi chigadzirwa chine saizi yakanaka kwazvo uye yakakodzera kusefa chaiko. Inowanzoshandiswa pamwe chete nemamwe mafirita aids. Iyo yakaoma chigadzirwa inonyanya kujeka yero, asiwo mukaka chena uye grey grey.

②Calcined zvigadzirwa Zvinhu zvakacheneswa, zvakaomeswa uye zvakapwanyika diatomite mbishi zvinopihwa muchoto chinotenderera, chakaverengerwa patembiricha ye800-1200 ° C, yobva yapwanywa uye yakamurwa kuti iwane zvigadzirwa zvecalcined. Kuenzaniswa neyakaoma zvigadzirwa, iyo permeability yezvigadzirwa zve calcined zvinodarika katatu zvakakwirira. Zvigadzirwa zve calcined kazhinji zvitsvuku zvitsvuku.

③Flux calcined zvigadzirwaMushure mekucheneswa, kuomeswa uye kupwanya, iyo diatomite mbishi inowedzerwa nekashoma sodium carbonate, sodium chloride uye zvimwe zvinoyerera zvinhu, uye zvino calcined pakupisa kwe900-1200 ° C. Mushure mekupwanya uye chidimbu saizi kurongedza uye kuenzana, iyo flux calcined chigadzirwa inowanikwa. . Iyo permeability ye flux calcined chigadzirwa inowedzera zvakanyanya, iyo inopfuura makumi maviri iyo yechigadzirwa chakaoma. Iyo flux calcined zvigadzirwa zvinonyanya kuchena, uye yakareruka pink kana iyo Fe2O3 yemukati yakakwira kana huwandu hwekuyerera hudiki.

Diatomite sefa inobatsira kusefa maitiro

Iyo yekusefa mhedzisiro yediatomite sefa yekubatsira inonyanya kuitwa kuburikidza neanotevera mabasa matatu:

1.Sieving effect

Uku ndiko kusefa kwepamusoro. Kana iyo mvura inoyerera kuburikidza nepasi diatomaceous, pores yepasi diatomaceous iduku kudarika hukuru hwezvikamu zvehutsvina husina kuchena, kuitira kuti tsvina dzisina kuchena dzirege kupfuura uye dzinobatwa. Mhedzisiro iyi inonzi sieving. Muchokwadi, pamusoro pekeke resefa inogona kutariswa sesefa yepasi ine yakaenzana avhareji pore saizi. Kana hupamhi hwezvikamu zvakasimba zvisingasviki (kana zvishoma zvishoma kudarika) dhayamita ye pores ye diatomite, zvimedu zvakasimba "zvichapepetwa kubva pakumiswa". Kupatsanura kunze, tamba chinzvimbo chekusefa pamusoro.
2. Zvakadzika mhedzisiro

Iyo yakadzika mhedzisiro ndeyekuchengeta mhedzisiro yekudzika filtration. Mukutsvaira kwakadzika, nzira yekuparadzanisa inongoitika mu "mukati" yepakati. Chikamu chezvimedu zvidiki zvisina kuchena zvinopinda pamusoro pekeke resefa zvakavharwa neiyo tortuous microporous chiteshi mukati mediatomaceous pasi uye madiki pores mukati mesefa keke. Rudzi urwu rwezvikamu zvinowanzova diki pane ma micropores ediatomaceous pasi. Kana zvimedu zvinorova madziro echiteshi, zvinogona kusiya kuyerera kwemvura. Zvisinei, kana inogona kusvika panguva ino inobva pane simba risina simba uye kushorwa kwezvikamu. Balance, rudzi urwu rwekubata uye kuongorora kwakafanana muzvisikwa, zvese ndezvemuchina chiito. Iko kugona kusefa kunze kwakasimba zvimedu zvinongoenderana nehukuru hwehukama uye chimiro chezvimedu zvakasimba uye pores.

3.Adsorption

Iyo adsorption mhedzisiro yakasiyana zvachose kubva kune maviri ari pamusoro ekusefa nzira. Mhedzisiro iyi inogona kunyatso kutorwa seye electrokinetic kukwezva, iyo inonyanya kuenderana nepamusoro pezvinhu zvezvikamu zvakasimba uye pasi diatomaceous pacharo. Kana zvimedu zvine maburi madiki emukati muvhu re diatomaceous parinodhumhana pamusoro pevhu remukati repasi diatomaceous, zvinokwezvwa nemhosva dzakapesana, kana zvimedu zvinokwezvana kuti zviumbe masumbu uye kunamatira kune diatomaceous pasi. Aya ese adsorption maitiro.

Iyo adsorption mhedzisiro yakaoma kupfuura iyo miviri yapfuura mhedzisiro. Zvinowanzotendwa kuti chikonzero nei zvimedu zvidiki zvidiki pane dhayamita yepore zvakabatwa zvakanyanya nekuda kwe:

(1) Intermolecular forces (inonziwo van der Waals attraction), kusanganisira zvachose dipole, induced dipole uye pakarepo dipole;

(2) Kuvapo kweZeta zvinogona;

(3) Ion kuchinjana maitiro.
